Dialog: Change event cancelled when opening modal dialog from another modal dialog

[kyle.davis]

When opening a modal dialog from a change event on an existing modal dialog, the change event is cancelled.

I guess this is a bug, maybe...

You're opening a modal dialog during the change event. The change event has not yet finished, but the new modal dialog now has focus, which means that any and all events that occur outside of the dialog will be cancelled.

We do explicitly prevent this from happening for the first modal dialog that is opened, but I'm not sure we can really handle this elegantly. We'd need a flag to signify that the modal event handler should ignore the event and set that on open and unset it with a delay. I don't think this is worth looking at until we can determine if .ui-front is a viable solution to the modal functionality.

FWIW, this is horrible UX.

If we can handle this in the dialog rewrite we should other wise this seems like an edge case that is pretty hard to handle.
